The Renthal TwinWall handlebar is a
new concept from Renthal. A large diameter, double-skinned
handlebar which combines immense strength, good resilience and a
virtual guarantee against fatigue failure. |
| Much information which
accompanies products is just advertising literature which expound
only virtues and never discusses the dilemma of product choice. In
this discussion of the Renthal TwinWall, we have tried to be
different. We give you the facts and the explanations behind the
facts. We have included explanations even if they have a negative
content because we believe a Renthal purchaser has mechanical
knowledge and an appreciation of engineering design. We very much
hope that you find this information interesting and informative. |

This following section explains the
concept, development and construction of the handlebar and is set out
in the form of questions and replies. The questions are based on those

TwinWall handlebar throughout its long process of development and
testing.
|

|
2 |
Why a large diameter handlebar
from Renthal ? |
|
3 |

the handlebar? |
|
14 |
Which teams have helped with the
testing of the Renthal TwinWall? |
|
15 |
Why do you need all this endless
rider testing, surely with modern technology you can simulate and
calculate almost everything beforehand? |
